A@ne ,of thelines 7,5 is led. through 'a' solenoid :operated'switch 39.

yThe coil of the solenoid switch 39 is energiied 'by a control circuit through the lines apparatus a.bovedescribed is such asl willstop the reel A. lift thedislr 9 and. operatathe pusher to 4push the coiled rod bundle Y cated at78.v Y

Yscribed is as follows:

'switch' 39 'to break the circuit Vthe lheader 55 byy means of pipe '57, valve'ports .chamber 30a, whichis supplied Ito the cham- Vmoved to its uppermost limit it will uncover from the reelonto the conveyer table indi- The operation of the apparatus above Vde- Cam lever 32 being in position M and reel is in operation. Movement of the lever 32 to position N will cause the lever to pivot about the vpin 33 and force they'lug 44El to ride over the head 41 of the cam rider 41a so as to depress the cam rider and switch arms 40 against the `spring 40C, thus operating the pilot switch 38 and deenergizing the solenoid to the motor 14 and stopping the reel.

The cam lever is then moved to position O, anddue to the stoplug 45a being in en- Y gagement with thelevers 34 at the terminationof 4thefirst lever movement, the levers 34 :will Vbe compelled to follow the cam lever in 31", 31, pipe 59 and simple ldifferential cylin- .derqport 29,a into cylinder chamber y30, op-

posing constant `fluidpressure inthe cylinder ber from the header 55 by means of the pipes and 161 and port 29". c

Thev entry rof fluid pressureto the ,simple diierential cylinder chamber 30 causes the piston to move vand .by means ofthe ydirect connection operate the three-way valve 28 so -as to permit Huid under pressure to -low from the header`55 to the vreel lift cylinder 7 by meansofpipe 60, ports 28b and 28a of valve 28, pipe 63a andcylinder port 1.5. f

Admission oiluid under pressure to the cylinder 7 through the port 15 will cause the piston 6 to move upwardly, therebylifting `the reel disk 9.- When the piston 6a has the port 16 and permit fluid under pressure e toflowthrough the pipe 464 and port 26ainto :the chamber 27 of the compound differential cylinder 26. f i

The fluid entering .the chamber 27 'of the `cylinder 26 will loppose ythe constantluid pressure in kthe chamber 27b of the cylinder V'26. which is suppliedjfrom the header 55byV meansffof thepipe 62jand-63 and port 26". vThe fluid entering the-chamber 27 causes .the piston to move tothe right which by direct# connection operates the four-way operating valve 25, permitting fluid pressure to flow from the header 55 into the rearend of the rod pusher cylinder 21 by means of pipe 62,

asf

ports 25by and 2,5a ofvalve 25, pipe 65 and 13o pusher `cylinder port 22, thus operating Lthe cylinder 21 to move the 'pusher head 19 torwardly and push the coiled rod ,from the reel onto theeonveyer bed 78. As the cylinder 21 is yoperated in the forward direction the fluid in the forward end of ythe cylinder will ybe i rao discharged through the port V23, pipe 66, `ports `25c and 25d of valve 25, and pipe 67 to drain 56.

After the above operation which unloads the coiled rod from the reel, the cam lever .32 is moved to the position R. The first part of the reverse movement causes the lever 32 to .pivot about the pin 33, until stop lugs 45 engage the lower levers 34. The cam rider 41l and pilot switch 38 vare"unaffected by this movement, ldue to the fact that lugs 43 on the levers 34 are over the arms 42 of the cam rider. The continued reverse .movement .of the lever 32 will cause the vlower levers 34 to move with the lever 32 as a unit pivoting about the pin 35. When the `cam lever 32 has reached its position R, the levers 34 will have resumed their vertical position moving the lugs 43 from the arms 42 and reversing the pilot valve 31 through connecting rod 46 and .bellbranlr lever 48 and connecting-rod 49. The pilot switch 38 still remains open, however, due to the tact that lug 44 on the lever 32 is moved over the head 41 of cam rider 41a before the lugs 43 are moved from the arms 42.

rlhe reversal of the pilot valve 31 moves the valve to waste position, permitting fluid pressure in the simple dilerential cylinder 'chamber 30 to waste through port 29a, pipe 59, ports 31a and 31 of vpilot valve 31, and pipe 53 to drain 56. ,Y

With the establishing of the above communications the fluid pressure in the `cha-m- Vber 30a of the cylinder 29 will act to cause the piston to move to the lett and by direct connections operate the three-way valve 28 fro its waste position. lll/Then .the valve is operated as labove described the fluid in the reel lift cylinder 7 will waste to the drain 56 through the port 15, pipe 63a, ports 28"L and 28c lof valve 28, and pipe'68.

As the pressure is released from the reel lift cylinder 7 the piston 6a vill be moved downward by gravity, thus closing port 16 and releasing the pressure `in the vcoinpou-nd differential cylinder chamber 27, through cylinder port 26a, pipe 64, reel liftcylinder porte 16 and 17, and pipe 70.

1With the waste ot the fluid pressure from the chamber 27 of cylinder 26, the constant tluid pressure in chamber 2'7" will act to cause the piston to move to the left, and bythe direct connections operate the four-way valve 25 'to permit fluid pressure from the header 55 to iow through the pipe 62, ports 25h and 25c of valve 25, and pipe 66 to the front end of pusher cylinder 21 through port 23, thus reversing pusher cylinder` 21 to retract the pusher headl). The 'fluid from the rear end of the cylinder 21 will be wasted through port 22, pipe 65, ports 25a .and 25d of valve 25, l

:and pipe=67 to .drain 56.

'l'lhe pusher head being retracted, the .lever 321s then returned to its initial position M,

4causing it to pivot about pin 33and thus :mov-

ing lug 44 from over the rcam rider head 41 and permitting the switch arm 40 .to raise to contact or circuit making position. The making of the control'circuit by the pilot switch 38 will energize the coil of switch 39, thereby attracting the bridge contact element of this switch and completing the power circuit to motor 14 which is again started to rotate'the reel.

During the forward movement of the pusher it may become necessary, due to interference, to stop or retard the operation of .the

pusher. This is accomplished by the opera-'1' tor pulling the emergency pusher control f lever 53 down into the position X, which will operate the three-way pilot valve 52 and permit -luid under pressure to flow from the header 55, through pipe 71, ports 52b and 52a' of valve 52, pipe 72, and port 26b of cylinder 26 into the chamber 27a of-said cylinder. The admission of the fluid under pressure to the chamber 27a will balance the vfluid pressure in the chamber 27 and permit the fluid pressure in the chamber 27b to act, causing the piston to move to the left so as to shift the valve 25 and permit fluid pressure to 'ii-ow from the header 55 through pipe 62, por-ts 25b and 25c of valve 25, and pipe 66 to the pusher cylinder port 23. The admission of liuid through the port 23 will cause the piston of the cylinder 21 to move rearwardly retracting the pusher head 19. As the piston in the cylinder 21 moves rearwardly the fluid in'l the rear of the piston will be wasted through the port 22, pipe l65, ports 25a and 25d of valve 25, and pipe 67 to drain 56. If the pusher operating cylinder 21 has not been operated to advance the pusher head 19 prior to the op- L eration of the lever 53 the operation of the lever 53 will simply serve to maintain pressure in the forward end of the cylinder 21 and prevent operation of said cylinder.

When the lever 53 is returned to its normal position the valve 52 will be moved to its waste position, releasing the pressure in chamber 27a of cylinder 26 by wasting the vfluid into drain 56 through the port 26h, pipe ered without aifecting the pusher mechanism "1 ico ias lagig 'as 'the lever 53 kremains inthe, posif tion i While we have shown and described one specific embodiment of our invention, it will be. understood that we do not wish to 4be limited thereto since various modifications may be 'made without'departing from the scope thereof, as defined in the appended claims.
